Efficient electron transport: The effect of two solution-processed electron-transport layers, PFN and ZnO nanoparticles, on the performance of small-molecule-based devices is investigated, and improved power conversion efficiencies are achieved. The combination of reduced bimolecular recombination and increased photon absorption contribute to the improved performance.
